v:rn/zrrzovrnm'ENT IN MECHANISM ron oPeRA'rING 'ras NIPPERS' or comma- MACHINES.

The Schedule referred to in these Letters Patent and making part or the sarna.

ToA allhvhom may con-cern Be itknown that I, HORACE DANIELs, of Pawtucket, in the county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Mechanism for Operating the Nipper-Jaw ill-Cotton- Oombing Machines and I do hereby declare the fol. llowing to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, makug a part of this specification, in which- Fignre 1 representar-in perspective, so much of a coton-combin g machine as will illustrate my invention, an

.Figure 2 represents a vertical longitudinal section vthrough the same.

Similar `letters of reference, where they occur in the separate figures, denote like parts of-the machine in both of the drawings.

i My invention consists in the mechanism for operating the nipperjaw in cotton -combing machines, whereby a very simple and edicient means of .accomplishing this object is obtained. l

Toenahle others skilled in the art to make and use my invention, I will.'proceed to describe the same in connection, with the drawings.

A represents a portion of the frame, and B, a portion of the main cylinder or doffer of any known combing-machine, and suli'icient in detail to illustrate the application of my invention thereto.

Onthe main driving, or any other suitable rotating shaft C, of the cotton or other libre-combing machine,

there is a crank or wrist-wheel, D, to the wrista, on

which, one end of a connecting-rod, E, is attached, the other end of said rod being attached'toa crank-arm, F, on the shaft G, which shaft carries the nippel-s, and vibrates them between the feeding-point, where they take a tuft of cotton, or other material to be combed, 'and the cylinder'B, where' the tnft; is deliveredto'be afterward operated upon as is comnicnin machines fol Vthis purpose. i

The shaft G receives a rocking motion only from its connections, and not a continuously-rotating motion, but the gear-wheel H on said rocking shaft has a continuons rotary motion on and sometimes with the shaft, as will be explained.

The nippers are arranged on the shaft G as follows:

Y Arms b b are permanently arranged on the lshaft G,

near its ends, but inside of the main frame A, and'upon the outer en'ds of these arms, and extending from one to the other,is permanently arranged one of the nipper-Jaws c. i v

. In bearings ldon said arms b b, the journals of a rocking shaft, f, are arranged, and can turn while the said shaft travels with said arms. Upon this rocking-shaft f there are arms g, upon the ends of which, and extending. from one to the other, and beyond them, is arranged the hinged or workingjaw h of the nippers; said latter or `hinged jaw, when closed, shutting down upon, or nearly upon the edge of its mate or fellow c, and both moving and working4 so as to take the cotton, or other material to be combed, from th'e feeding-point or edge/i, and carrying it, as before mentioned, up and delivering it to the cylinder B.

Upon the shaft j' is secured atappet-arm, I, which extends rearward, (calling that the front of the machine where the material is fed in,) so as to come within the path of a cam, J, that is fast to-and rotates with the gear H, that is loose on what I have termed the nipper-shaft G, so as to be struck and operated by said cam at every rotation of the gear-Q-wheel H;` and from said shaft f to the shaft Gr, thereentends a rubber or other spring, j, which is expanded,'and partially winds around said shaft, to which its ends are respectively fastened, so that the contraction of said spring may open the hinged jaw h, or raise it, after the cam J has closed it, and passed beyond the influence of thetap pet I, by which the nipper-jaws were held closed.

On the shaft O, which makes a continuons rotation, there-is a gear-wheel, K, 'which gears with and turns an intermediate gear, L, on a shaft, M, and this interl mediate gear works into and gives a continuous motion to the gear H, which of course mustbe loose on- A its shaft G, which only rocks, but does not rotate conf tinnously in one and the same direction, as thewheel H does and must do. Y

It willthns be perceived that the nippers are moved to the point where they take the cotton, or other Ina--l ferial to be combed, and then to the cylinder, to deliver it by -the rocking shaft G, while'the movable jaw of the pair is closed upon the tuft, and held there by the rotation of the gear H and cam J on said shaft, and opened by the reaction of the spring'j connected to and partially or wholly encircling the two shafts G and f.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, ist I n combination with a pair of nippersV that move in the'arc of a circle, for taking and.carrying'the material tobe combed from the feeding-point to the carry.
